finsjnn'retn JOINT.

To all whom it may concern." v Y Be it known that-l, JOHN J. MEYER, a citizen of the United States, and a resident of the city oi New York, borough of Manhattan, in the county and State of New York, have invented a new and improved Insertable Joint, otfwhich the following is a full, clear, and exact description.

This invention relates 'to an inser'table joint for soil pipes and has for an object to provide an improved construction lwherein a joint may' be readily made without disturbing theupper part of a pipe or the lower part.

l@ A further object of the inventionis to provide an improved'formrof joint which is a division in part of my prior application, Serial No. 480,294. t'

A further object of the invention is to provide a joint for soil pipes and the like wherein the joint may be expansib'le with or without the insertion of an auxiliary member and wherein an auxiliary member when used may be inserted laterally.

215 Another object is 'to proyide a method tor joining two pipe sections, each'having one mitered or slanted end, ywith a rigidly fixed pipe line to permit oit leasy falling together into a tubular alignment within a pipe coupling. Y

An additional kobject is to provide an insertable'joint'for soil pipes wherein a .specially constructed hub is provided which y acts in thecapacity of an ordinary hub and in addition as enclosing andretaining means for inserted portions of pipes and as aconnecting member for connecting the inserted section with the 4superimposed section. In the-accompanying drawingf Figure 1 is ra fragmentary View of'a soil pipe extending through two floors'- ol? a building-with ycertain parts' broken awa'y illustratingl an kembodiment' of the invention v f Y Figure 2 is an enlarged fragmentary view of ,the uppery part lof the-joint shown in Figurel, the 'parts/being in: the position immediately after insertion.

Figure 6 is a view similar to Figure y2 but showing a further modified form of the invention wherein the inserted pipe is formed of two pieces only.

Figure 7 is a viewsimilar to Figure 6 but showing an insert or sleeve section for securing an additional expansion.

Figure 8 is aV view vsimilar to Figure 5 but showing a modified form of the invention. V

Referring to the accompanying drawing by numerals, 1 and 2 indicate the iioors of a building through which a soil pipe 3 eX- .tends The soil pipe may be of any desired height and connected in any desired manner with the various fittings of the building. Under some circumstances, it may be desired to add a new section to the soil pipe at' some convenient point, vas for instance, section 4 which isa branch section of pipe designed to present an auxiliary opening.

When it is desired to putin a new section similar to section 4, it will be necessaryto remove one of the sections of the soil pipe and in such removal the particular section is broken or cut. After thedesired section or sections have been removed, pipe 4 is' inserted as shown in Figure land then an inserted joint section provided/,which consists of a lower section 5 of the same diameter throughout and adapted at its lowerend'to fit into the bell'or hubo of section 4 while at its upper end it is provided with threads '7 for Vreceiving the internallyI threaded section 8 of the bell or hub 9.

' It will be noted that the hub or bell 9 is provided with an upper portion 17 .which is in the form of the usual bell, said upper portion merging into a thickened portion 18 which carries a shoulder 15, said thickened portion also merging into an intermediate section( 19 and said intermediate section merging into alower section 20, which lower section carries the annular flange 16 and the threaded' section y8.y It will be noted ythat the upperfend ofthe section'is an appreciable distance below the lower end ofthe superimposed section 10. To'take care of this space and at the same time provide a proper support for the section 10 and other sections 'above the same, a nipple or sleeve 11' is provided, `which sleeve y,or nipple is formed rwith an inclined or cani bottom 12 co-acting with the slanting or inclined top 13. By thisA construction and arrangement, the section 5 may be placed in the bell or hub 6 and then swung over to a proper position in engagement with the nipple 11. If the distance between the section 4 and section 10 is too great to allow a contact as shown in Figure 1, the section 5 may be rotated as shown in Figure 6 to the desired extent to take up the distance. It will thus be seen that this form of the invention provides an adjustment or an expansion to take up slight difference in length and at the same time maintain a support for the superimposed pipe section. After thefsectiony 5 has been adjusted to the position shown in Figure 1 or that shown in Figure 6, the hub may be screwed into position as illustrated in Figure 1. Under some circumstances, it may be desired to add some 'additional spacing and supporting member and when this is the case the parts may be separated and a supporting section 14 inserted between the cam faces 24 and 25, said section being held in place by the hub 9 when it is moveddown to its operative position as shown in Figure 1.

tubular structure providedwith a flange 24 similar to the flange of the nipple 11. The

exterior diameter of the sleeve 11 is slightly7 i less than the exterior diameter of the section 5 so that the threaded portion S may slide thereover. Associated with the sleevell is j ture 28V formed by the cam members 25 and 26, one or both of the sections may be ro- Vtated and thereby produce an expansion.

The more that one member is rotated in respect to the other the greater will be the separation at one time but they` will always remain in contact whereby a proper support for the superimposed section 10 and other sections thereabove will be provided. After the cam members 25 and V26 have been properly adjusted, the hub 9 is moved downv as shown in Figure 5 and screwed intoposition after which theliilling 29`is provided In Figure v8, another form ofthe invention is shown wherein the section 5" is identical with section 5 shown inV Figure 4 but the hub 9 is arranged with -a single inwardly extending flange which is threaded on-its interior surface so as to be screwed onto pipe 5'. `In this form of the invention,

In Figures 4 and 5, a modified construction is shown wherein the nipple 11 1s a the cam sections 25 and 26 are used and are each made of a greater height than the thickness of the flange 30 though the outside diameter is less than the diameter of the threaded opening in the hub. It is understood that the nipples or sleeves 11, 11, 25 and 26 and the slanted end of section 5 may be slightly less in eXterior diameter than thel sections 5 and 10 and that cam or slanted pipe ends are mainly intended to allow the per end, and a nipple loosely positioned in 1 said hub having a slanting end co-acting with the slanting end of said'pipe section.

An insertable joint, comprising a pipe section having a slanting upper end, an ei:- ternally threaded portion near theA upper end, a hub having a threaded portion adapted to be screwed onto the threaded portion of said section, and a tubular nipple having a slanting bottom for fitting the slanting top of said section1 said nipple having an annular flange at the upper end acting as a false bottom for said hub.

3. An insertable joint for soil pipes and the like, comprising two pipe sections, a pipe coupling adapted to confine one end of'- each of the said pipe sections within the hub in tubular alignment and to form a water ti ght joint. the said two pipe sections within the hub to have slanted registering faces to permit of easy falling together when being assembled. Y

4. An insertable joint for soil pipes and the like, comprising two pipe sections, a pipe coupling adapted to confine one end of' each of said pipe sections within the hub in tubular alignment and to'form a water tight joint7 the said two pipeends within the hub to have slanted registering faces to permit of easy falling together when being assembled, said ypipe coupling having one end threaded on one of the said pipe sections and its other end adapted for a filler joint around the second pipe end.

5. In combination with a-soil pipe line and the like having a branch outlet, an insertable joint comprising two or more sections of pipe having slanted or mitered faces to facilitate the falling together of the sections into tubular alignment, and a coupling o r hub adapted to enclose the portions of ist negates the sections having the mitered or slanted faces and to form a water or gas tight oint.

6. An insertable joint, comprising a pipe section, a removable hub having the lower portion internally threaded, said pipe being externally threaded at the upper end, and a pair of cam members capable of being positioned on the upper end of said section by a lateral movement, the upper end of said sec'- tion and said cam members being positioned within said hub.

7. An insertable joint, comprising a pipe section threaded at the upper end, a removable hub therefor, and a pair of cam members positioned within Lthe hub when the hub is screwed onto said threaded section, said cam members being in the form of rings and each ring having a tapering or slanting face whereby when one ring is rotated in respect to the other they will be expanded or contracted according to the direction of rotation.

8. An insertable joint for soil pipes and the like, comprising a pipe section threaded exteriorly at one end, a removable hub formed with a threaded portion normally screwed onto the threaded portion of said section, and a combined supporting and spacing ring resting on said section, said ring being formed in two parts having registering cam faces capable of causing the distance between the opposite end of the sleeve to be varied according to the position of the sections, and to allow the pipe section to fall into position easily by reason of the slanting ends of said ring sections.

9. An insertable joint for soil pipes and the like, comprising a section having eX- ternal threads adjacent one end thereof, a tubular ring divided into two parts, one part of said ring constituting one pipe end and the other part of said rin constituting a second pipe end co-acting with the first mentioned pipe end, said ring parts being formed so that theirengaging faces will be on a slant to facilitate the movement into position of said pipe ends in alignment thereof, and a hub removably mounted on the externally threaded pipe end.
